Kate Middleton, 37, and Prince William, 36, expanded their brood last year when they welcomed their third child Prince Louis, nine months, to join Prince George, five, and Princess Charlotte, three. The Duke and Duchess of Cambridge are known to keep their children’s upbringings out of the spotlight, but occasionally reveal small insights into life at home with the royal brood. Catherine recently spoke openly about the pressures of motherhood, while Prince William has frequently mentioned how energetic his children are. While George and Charlotte don’t have rules as strict as their great grandmother Queen Elizabeth II, 92, would have had when she was growing up, Kate and William have spoken out about their parenting style.
